Two sides of the same coin. The corrupted and the holy.
The corrupted, being inspired by what the character may have become, from certain loss of their love. To change for the dark, to corrupt themselves into turmoil. Another idea of the other side of this coin, to be the holy. An alternative road, where the angel, the light, was to delve into this chaos, to put a stop to it. To justify and save herself, including those around her in which she holds dear to herself.
Two sides of the same coin. Same person, different paths.
